Forget the romance of dinner in a smoky Italian restaurant. Italy has banned smoking in all indoor spaces, including bars and restaurants, unless their smoking section is separated from the rest of the building by continuous floor-to-ceiling walls and with its own ventilation system. Most restaurants are too small to install a separate section. And they now face a $2,600 fine and loss of their business license if they don't report those who light up. Smokers face smaller fines.
